(Embodiment 1)
Next, an embodiment of a hot water cleaning apparatus provided with a local cleaning means in the toilet seat according to the present invention will be described.

  As shown in FIGS. 1 and 2, a water supply pipe 1 connected to a water pipe is connected to a water pipe direct connection adapter section 2, and water to be washed water is taken into the hot water washing apparatus from here. This water is heated by the heat exchanger 3, pressurized by the water pump 4, passes through the flow path regulating valve 5, and after adjusting the flow rate there, two local parts for anus and bidet, which are local washing means, are used. The water is branched into the cleaning nozzles 6 and 6 and the nozzle cleaning means 7 which becomes a dirt cleaning means for washing away the dirt of these local cleaning nozzles 6 and 6.

  When the local cleaning nozzles 6 and 6 do not perform local cleaning as shown in FIGS. 3 and 4, the local cleaning nozzles 6 and 6 are retracted from the local cleaning unit and stored in the nozzle storage unit 8 serving as a storage unit. In some cases, it is configured such that it moves forward from the rear center of the ring-shaped toilet seat 10 provided with the main body 9 of the hot water cleaning device from the nozzle storage portion 8 so as to move forward and backward.

  The nozzle housing portion 8 is a guide cylinder 11 that forms upper, lower, left and right side walls, a lid 12 as means for opening and closing a front opening through which the local cleaning nozzles 6 and 6 enter and exit, and guide means for guiding the movement of the local cleaning nozzles 6 and 6. The rib 14 (shown in FIG. 6) is formed, and a substantially sealed space is maintained by the lid 12 being closed. The substantially sealed space has a structure including a gap due to an error in assembly of the guide cylinder 11 and the lid 12 and the like. The guide tube 11 may be an independent member for forming a substantially sealed space. However, in the present embodiment, the local cleaning nozzles 6 and 6 are used for local cleaning, which is a space surrounded by the nozzle storage portion 8 and the toilet seat 10. A guide member is used to move between appropriate cleaning positions.

  The local cleaning nozzles 6 and 6 can move between a standby position and a local cleaning position in the nozzle storage portion 8 by the force of a drive source (not shown) using water pressure or electricity. The local cleaning nozzle unit 13 is configured together with 8 etc. Then, as shown in FIG. 5, when the local cleaning nozzle 6 is in the local cleaning position, the lid 12 is pushed up and opened by the moving force of the local cleaning nozzles 6, 6, but the local cleaning nozzle 6 enters the nozzle housing 8. The upper end of the lid 12 is pivotally supported on the upper edge end portion of the guide tube 11 located on the distal end side of the local cleaning nozzles 6 and 6 so that the lid 12 is closed by its own weight when retracted and in the standby position.

As shown in FIG. 6, the nozzle storage portion 8 is provided with ribs 14 along the circular outer shape of the local cleaning nozzle 6 inside the guide tube 11, and a substantially sealed space is formed by closing the lid 12. Forming. That is, the nozzle accommodating portion 8 accommodates the tip portion of the local cleaning nozzle 6 where the washing water ejection hole 6 a is located in the space surrounded by the rib 14, the lid 12 and the guide cylinder 11. In the figure, reference numeral 15 denotes a central partition wall for partitioning the two local washing nozzles 6, 6 for anus and bidet.

  Furthermore, in order to improve the substantially hermeticity of the nozzle housing portion 8, it is possible to provide a rubber packing that contacts the local cleaning nozzle 6 at the end of the rib 14 inside the guide tube 11. The lid 12 is not only closed by its own weight, but also as shown in FIG. 7A, a compression spring 17 as a closing urging means is provided at the upper part of the center of the rotary shaft 16 provided at the upper edge of the guide cylinder 11 in the drawing. In the configuration in which the lid 12 is always urged in the closing direction, the lid 12 is always closed, and the local cleaning nozzle 6 is opened by the force of the local cleaning nozzle 6 that advances from the nozzle housing 8 to the local cleaning position by power during local cleaning. As shown in FIG. 7 (b), the lid 12 has a mechanism that opens and closes in conjunction with a local cleaning start and cleaning stop command to the local cleaning nozzle 6 by moving a release 19 with a motor 18 as an electric opening / closing means. It is also possible to close the nozzle storage portion 8 more effectively.

  As shown in FIG. 1, mist generating means (also referred to as atomization generating means) 20 supplies tap water taken into the hot water cleaning device to a water storage section 20a from a water channel branched from a pipe connected to local cleaning water. It is configured to be atomized by the sonic vibration device 20 b to become mist, and to naturally flow from the inlet 21 that opens into the nozzle storage portion 8 to be filled. The mist generating means 20 may be any of those caused by heat, those generated by a member that rotates at high speed, those caused by a high voltage, those caused by electrostatic atomization, etc. in addition to ultrasonic vibration.

  The inflow port 21 is provided on the wall of the guide cylinder 12 of the nozzle storage unit 8 at a position substantially the same as or higher than the position of the ejection hole 6a of the local cleaning nozzle 6 stored in the nozzle storage unit 8. The mist that has flowed into the nozzle storage portion 8 flows downward, is naturally guided to the vicinity of the ejection hole 6a, and can be efficiently transported without having a special step for transporting the mist. In order to send the mist from the mist generating means 20 to the nozzle housing portion 8, a conveying means such as an electric fan may be used.

  In addition, as shown in FIG. 1, in the case of a hot water washing apparatus having a structure of a drain port 22 for draining a part of water taken into the hot water washing apparatus as surplus water when the flow rate used for local washing may be small. The surplus water can be effectively utilized by branching from the surplus water drainage channel 22a and supplying the water to the mist generating means 20.

  Now, since the mist generating means 20 fills the generated mist into the nozzle storage portion 8 which is a substantially sealed space, the local cleaning nozzles 6 and 6 as well as the inside of the nozzle storage portion 8 can be subjected to mist cleaning. Since the mist has a particle size of about several to 100 μm, it can float in the air, and the local cleaning nozzle 6 is more complicated than the case where the local cleaning nozzle is washed by applying water or hot water. It can reach the back of a simple shape and can be cleaned efficiently.

  In other words, not only the tip of the local cleaning nozzle 6 where the mist is likely to get dirty, but also penetrates through the details of the complicatedly shaped ejection holes 6a, so that the attached dirt is surely floated and can be put into a mist cleaning state that is easy to remove. The mist concentration may be sufficiently increased in the nozzle housing portion 8 to wash away with water adhering to the surface of the local cleaning nozzle 6, or to be washed away with water or warm water. It is possible to reliably wash away dirt by performing an operation such as wiping.

  Further, the medicine adding means 23 is connected to the upper water passage of the mist generating means 20 so that the medicine is mixed with water and accumulated in the water storage part 20a of the mist generating means 20, and the mist generated from the mist generating means 20 is sterilized and deodorized. In this configuration, a chemical having an effect of removing dirt is added, and the inside of the local cleaning nozzle 6 and the nozzle storage portion 8 is subjected to mist cleaning with the mist added with the chemical.

  In general, the filth contains oil, which cannot be removed by conventional scrubbing with water or hot water, and has been a cause of soiling of the local cleaning nozzle 6 due to its accumulation. As described above, the mist to which the drug is added can deliver the drug to every corner of the local cleaning nozzle 6 having a complicated shape, and the cleaning effect can be further enhanced.

  Further, as shown in FIG. 8, the drainage means 11 a is configured by providing a notch for drainage or the like on the bottom surface of the guide tube 12 of the nozzle storage portion 8 (or from the bottom surface to the side surface of the guide tube 12). . Accordingly, the nozzle cleaning means 7 for cleaning the local cleaning nozzle 6 with hot water or water causes the local cleaning nozzle 6 and the nozzle storage portion 8 after cleaning in the local cleaning nozzle 6 and the nozzle storage portion 8 with the mist to which the medicine is added. Can be washed away with hot water or water, and the dirt that is easily removed by the medicine can be quickly washed out from the drainage means 11a into the toilet. In addition, you may make it drain using the clearance gap which arises on the assembly of the guide cylinder 11 and the lid | cover 12. FIG.

  The operation unit 24 is configured to send a command to the control means 25 to operate the hot water cleaning device by operating a button, and starts and stops the local cleaning by the local cleaning nozzles 6 and 6 as in the conventional device, and smells in the toilet. Deodorizing and stopping by the deodorizing device 26 for sucking and deodorizing, drying and stopping by the drying means 27 for drying the part to be cleaned after the local cleaning with warm air, and further the local cleaning nozzle 6 and the nozzle storage part 8 by the mist generating means 20 The mist cleaning and stop of the inside, the addition and stop of the medicine to the water by the medicine addition means 23 at the time of mist cleaning, and the washing and stop of the flushing by the nozzle cleaning means 7 in the local cleaning nozzle 6 and the nozzle storage part 8 are instructed thereafter. .

  The control means 25 is composed of a microcomputer and its peripheral circuits. As shown in FIG. 1, the control means 25 includes a water pump 4, a flow path adjusting valve 5, a local cleaning nozzle unit 13, a mist generating means 20, a drug adding means 23, a deodorizing device 26, A flow that is electrically connected to the drying means 27 and the like, and that incorporates a program for executing the operation and action of the hot water cleaning apparatus described below in response to a command from the operation unit 24, and in particular performs the mist cleaning shown in FIG. There is also a built-in program to execute

  In FIG. 1, 28 is a seating detection means provided on the lower side of the toilet seat 10 to detect whether the user is seated and separated and send a signal to the control means 25 to contribute to the control execution of the control means 25. In addition to the toilet seat, it may be provided in the main body 9 of the hot water washing apparatus or in the remote control device of the hot water washing apparatus, and may be a seating detection means that also serves as an entry detection means for the toilet room.

  In the above embodiment, when the user sits on the toilet seat 10, the deodorizing device 26 is operated by the control means 25, and when the user operates the operation unit 24 after the toilet, the following operations and actions are performed. That is, the local cleaning nozzle 6 pushes the lid 12 open and advances from the nozzle housing 8 to the local cleaning position of the toilet seat 10, and heat is generated from the ejection hole 6 a of the anal local cleaning nozzle 6 selected by the flow path adjustment valve 5. Hot water wash water that is instantaneously warmed by the exchanger 3 is jetted to wash the local area. After the local cleaning, when a stop command is issued from the operation unit 24, the local cleaning nozzle 6 moves backward from the cleaning position and is placed in a standby position in the nozzle storage unit 8, and the lid 12 is closed by its own weight. In addition, when a local drying command is given, the drying means 27 operates, and the portion to be cleaned wet by the local cleaning is dried with warm air, and when a drying stop command is given, the drying stops.

As shown in FIG. 9, in this embodiment, the mist generating means 20 is a local cleaning nozzle that is placed in the nozzle storage portion 8 where the lid 12 is closed and is in a standby position by the user at an arbitrary timing from the operation portion 24. When mist generation is commanded in step (hereinafter referred to as S) 1 in order to clean the mist 6, it is confirmed in S 2 whether the local cleaning nozzle 6 is stored in the nozzle storage unit 8. The mist is not generated and the process returns to S2, and the confirmation is repeated again.

  On the other hand, if the local cleaning nozzle 6 is housed in the nozzle storage unit 8 in S2, an error and generation instruction is given in S3, the mist generation unit 20 is operated by the control unit 25, and the ultrasonic vibration device 20b is operated from the water storage unit 20a. As a result, mist is generated and flows from the inlet 21 into the nozzle housing 8 with the lid 12 closed, and the mist is filled.

  Then, the tip of the local cleaning nozzle 6 and the details of the ejection hole 6a are covered with the mist and penetrate the attached dirt to float the dirt and make it easy to remove. Of course, if dirt also adheres to the inside of the nozzle housing 8 at this time, the same action as described above occurs and mist cleaning is performed.

  Of course, if the medicine adding means 23 is operated when the mist generating means 20 is operated and the medicine is mixed with water that becomes mist, the mist generated from the mist generating means 20 has the effect of sterilization, deodorization, and dirt removal. In addition, sterilization, deodorization, and dirt removal are added to the above-described mist cleaning.

  Accordingly, in the mist cleaning state in which the dirt in the local cleaning nozzle 6 and the nozzle storage portion 8 is floating and easily removed, and sterilization, deodorization and dirt removal are added to the mist cleaning. When the adjustment valve 5 is adjusted and the cleaning water flows out from the nozzle cleaning means 7, it falls into the local cleaning nozzle 6 and the nozzle storage portion 8, and dirt that has not been removed by conventional nozzle cleaning can be easily washed away and the nozzle storage portion 8. The drainage means 23 can be surely and quickly discharged, and can always be kept clean.

  Further, after the mist cleaning to which the medicine is added, not only can the dirt that is easily removed by the medicine in the local cleaning nozzle 6 and the nozzle housing portion 8 be easily washed away with hot water or water, but also the local cleaning nozzle 6. In addition, the adhered medicine in the nozzle housing portion 8 can be washed away at a time, and the local cleaning nozzle 6 and the nozzle housing portion 8 can be protected from the medicine.

  As described above, in the present embodiment, the mist generating means 20 generates mist when the local cleaning nozzle 6 controlled by the control means 25 and subjected to the local cleaning is stored in the nozzle storage section 8. The mist stays without waste in 8 and becomes a sufficient concentration. The local cleaning nozzle 6 including the ejection hole 6a touches the mist, and the dirt adhering thereto can be efficiently floated and easily removed. Therefore, in order to realize various jet forms, even if the mechanism of the local cleaning means has a more complicated internal configuration and parts configuration, it is ensured that the mist is efficiently distributed to the details and the dirt is floated. It is possible to easily clean and clean by washing.

  Further, the lid 12 changes into a closed position in which the nozzle housing 8 is closed and an open position as the local cleaning nozzles 6 and 6 move forward and backward, and a driving source for opening and closing the lid 12 is unnecessary. Thus, the structure can be simplified, and the presence of the lid 12 prevents the dirty water from inadvertently entering the nozzle storage portion 8 during stool and cleaning, and also prevents the adhesion of dirt.

  The cleaning by mist can be performed at an arbitrary timing according to the user's instruction. However, when the local cleaning nozzle 6 is in the cleaning position by opening the lid 12 from the nozzle storage unit 8, the cleaning of the local cleaning nozzle 6 is performed. Therefore, it is preferable to control so that mist can be generated only when the local cleaning nozzle is stored in the storage unit.

Therefore, only when the nozzle housing portion 8 is substantially sealed by the lid 12, the timing for the mist generation is a signal that is closed by providing a sensor or the like for detecting the open / closed state of the lid 12, or the backward movement of the local cleaning nozzles 6 and 6. It can be easily and accurately used by the control means 25 as a signal detected by a sensor or the like.

  In addition, since the lid 12 is provided at the upper edge end located on the tip end side of the local cleaning nozzle 6 in the nozzle storage portion 8 so as to be freely opened and closed, the lid 12 is opened by the movement of the local cleaning nozzle 6 due to advancement and retreat. It can be closed by its own weight to make a simple configuration.

  Further, since the lid 12 always closes the nozzle housing portion 8 by the compression spring 17, when the local cleaning nozzle 6 moves backward to the standby position, the nozzle housing portion 8 is reliably closed by following this movement. Eliminates mist leakage and enhances the effect of mist cleaning.

  Further, since the lid 12 opens and closes the nozzle storage portion 8 by the motor 18, the nozzle storage portion 8 is not inadvertently opened and closed, and the nozzle storage portion 8 can reliably function as a nozzle storage and mist cleaning chamber. It becomes possible.

  Further, since the nozzle storage portion 8 also uses the lid 12 and the rib 14 for opening and closing the nozzle storage portion 8 as constituent members of the storage portion, the local cleaning nozzle 6 is guided by the rib 14 and the drive is not peeled off. Of course, the configuration of the nozzle housing 8 can be simplified.

  In the above embodiment, the nozzle housing 8 and the local cleaning nozzle 6 in the mist cleaning state are washed away with the cleaning water from the nozzle cleaning means 7, but the inside of the nozzle housing 8 has a sufficient mist concentration. The dirt may be removed by rinsing with water adhering to the surface of the local cleaning nozzle 6 or by rinsing with water or warm water separately, or the user may remove the local cleaning nozzle 6 from the nozzle housing 8. It is also possible to make sure that the dirt is washed away by performing an operation such as wiping it out.

  In the above-described embodiment, both the local cleaning nozzle 6 and the nozzle storage unit 8 are in the mist cleaning state. However, at least only the local cleaning nozzle 6 that is easily contaminated may be used.

FIG. 10 is a schematic configuration diagram of a nozzle housing portion in the hot water cleaning apparatus according to Embodiment 2 of the present invention. The present embodiment has a configuration in which a vibration device is provided in the nozzle housing portion. In this respect, only the difference from the above-described invention of the first embodiment is the same as the other configurations and operations and effects. Referring to FIG. 9, the different parts will be mainly described.

  As shown in FIG. 10, the local cleaning nozzle 6 and the nozzle storage portion 8 of the first embodiment are connected to an ultrasonic vibration device 30 that is a vibration device, and are cleaned by mist or by hot water or water after the mist cleaning. The cleaning effect is enhanced by ultrasonic vibration during cleaning. The ultrasonic vibration device 30 is connected such that the local cleaning nozzle 6 is vibrated by the vibration transmission unit 31 that transmits vibration, and the guide cylinder 11 is vibrated by the vibration transmission unit 32, and is vibrated by the control means 25 that receives a command from the operation unit 24. And is to be stopped.

  In the above-described embodiment, the ultrasonic vibration device 30 controlled by the control unit 25 that has received a command from the operation unit 24 is operated when the mist cleaning by the mist generating unit 20 is started or after the mist cleaning has passed for a while. Then, the local cleaning nozzle 6 and the nozzle housing portion 8 are ultrasonically vibrated, respectively.

As a result, the dirt adhering to the local cleaning nozzle 6 and the nozzle storage portion 8 is becoming easier to remove by mist cleaning as described above, and is further subjected to vibration of the local cleaning nozzle 6 and the nozzle storage portion 8. It is easy to remove, and some of them are cleaned.

  Therefore, when the flow control valve 5 is adjusted by the command from the operation unit 24 and the cleaning water is discharged from the nozzle cleaning means 7, it falls into the local cleaning nozzle 6 and the nozzle storage unit 8, and does not drop in the conventional nozzle cleaning. The dirt can be washed out more easily and can be discharged more reliably and quickly from the drainage means 23 of the nozzle housing portion 8, and can always be kept clean.

  In the above embodiment, both the local cleaning nozzle 6 and the nozzle housing 8 are vibrated. However, at least only the local cleaning nozzle 6 that is easily contaminated may be used.

A light source 33 by an LED as a light emitting means is provided in the lower part of the side wall of one guide cylinder 11 constituting the nozzle housing portion 8 in the vicinity of The LED is waterproofed with a transparent cover member, and is controlled to be turned on and off by the control means 25 by operation of the operation unit 24. The central partition wall 15 has a front end face set to a length that is one step lower than the front opening edge of the guide tube 11 and illuminates two nozzle storage portions 8 arranged in parallel for anus and bidet with one LED. It is configured to be able to.

  In the above embodiment, when the local cleaning nozzles 6 and 6 are cleaned by mist or the local cleaning nozzles 6 and 6 are cleaned by hot water or water, both the local cleaning nozzles 6 6 is visible from the outside through the transparent lid 12a. Of course, the light source 33 is not limited to the LED, and may be another light source such as a planar light emitter.

  In particular, the light source 33 of the nozzle storage unit 8 can be turned on and off in addition to a configuration that is interlocked with mist cleaning or when washing away dirt after mist cleaning, so that the entire hot water cleaning apparatus can be turned on manually. It is also possible to turn on the lamp at the time of cleaning and visually check the state of the local cleaning nozzles 6 and 6 which are difficult to see.

  As described above, the inside of the nozzle storage portion 8 can be visually observed by the transparent lid 12a, and the mist cleaning status of the local cleaning nozzle 6 can be confirmed, so that a sense of security for the user can be obtained.

  Further, since the nozzle storage portion 8 includes a light source 33 in the vicinity and emits light in conjunction with the mist generation means 20 operated by the control means 25, it is possible to easily look into the nozzle storage portion 8 through the transparent lid 12a. Thus, confirmation of the mist cleaning effect can be ensured.

  Of course, in the case where the inside is not visible like the lid 12, the object can be achieved if the lid 12 is opened and the inside of the nozzle housing 8 is looked into. Further, the light source 33 and the transparent lid 12a effectively notify that the mist cleaning is being performed, and the user can grasp the operation state of the mist cleaning.
